FLEXIBLE RECEPTAGLE.

Specification of Letters Patent.

Patented June 16, 1908.

Application filed May 21, 1906. Serial No. 317,999.

- freely foldable receptacle for liquids and solids, the receptaclebeing flexible throughout so that it may be folded into small space andshipped without danger of breakage.

A further object of the invention is to provide a paper receptacle whichmay be employed for the sale and distribution of milk or other material,thus avoiding danger of infection from unclean bottles orsimilarreceptacles which are ordinarily employed for the purpose, andwhich must be washed after use.

A still further object of the invention is to provide an improved paperreceptacle, and to employ a closure of novel and simple but eflectiveconstruction which maybe readily inserted and locked in place after thereceptacle has been filled.

With these and other objects in View, as willmore fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts, hereinafter fullydescribed, illustrated in theaccompanying drawings, and particularly pointed out in the appendedclaims.

In the accompanying drawings :Figure 1 is a perspective view ofa'flexible receptacle constructed in accordance with the invention. Fig.2 is a sectional elevation of the same, showing one form of cap orclosure which may be employed. Fig. 3 is a detail perspective view ofthe cap detached. Fig. 4 is a detail perspective view of the receptaclefolded. I

Similar numerals of reference are employed to indicate correspondingarts throughout the several figures of the rawin s.

in carrying out the invention, the receptacle 10 is formed of aper orsimilar cheap material sufficiently exible throughout to permit foldingwithin a very small space, so that large iantities of the receptaclesmay be shippefl at comparatively small expense. The receptacles are madeof paper which has been treated with paraffin or other chemicalmaterial'torender it water proof, and in order to add to the stren th ofthe vessel, its upper face is contracted to form a neck 11, resemblingsomewhat the neck of an ordinary glass bottle. The paper is turned overat the top to form the mouth of the receptacle, and, also, to form aseating flange 12 against which the cap or cover 13 may engage.

The cap 13 is formed of paper, cardboard, or other suitable material,and is provided with a tab 14 that constitutes a hinge which ispreferably inserted under the bent edge of the pa er, and fastened inplace, the free edge 0 the cap being provided with a small string orcord 17 which may be grasped for the purpose of pulling the cap outwardagainst the flanged or inturned edge of the paper after the receptaclehas been filled,

and to empty the contents of the receptacle the cap may be forced inwardto its initial position.

These receptacles may be made at very small cost, and after being useda. single time may be thrown away or destroyed, so that the danger ofinfection from unclean bottles in constant use is avoided.

While the receptacles are specially valuable for the sale anddistribution of milk, they may, of course, be used for the reception ofliquids or solids of any nature.

I claim 1. A liquid receptacle having a body portion and a contractedneck portion formed of flexible Water proof material capable of beinfolded with its bottom and sides in para el planes, and a closureattached hingedly to the neck portion to hold the latter distended whenin its operative position and capable ofbein folded to occupy a positionin a plane para lel with the folded sides and bottom.

2. A liquid receptacle having a body portion and a contracted neckortion formed of flexible water proof materia capable of being foldedwith its side and bottom portions in parallel lanes, the u per edge ofthe neck portion eing inwar ly turned to form a downwardly or inwardlyfacing shoulder,

"and a closure of ri 'd material fitting snugly in and adapted to oldthe neck portion distended when said closure is in its normal position,and being hingedly connected with the neck portion to fold in a planeparallel with said side and bottom portions.

3. A liquid receptacle having a body portion and a contracted neckportion formed of flexible water proof material capable of beingfoldedwith the side and bottom fporbeing hingedly connected with theneck portions in parallel planes, the upper edge 0 the I neck portionbein inturned to form a downwardly or inwardly facing shoulder, theintion to fold in a plane parallel with the sides and bottom portions.-

In testimony that I claim the foregoing as 15 wardly turned portionbeing spaced from the my own, I have hereto aflixed my signature adaptedto hold the latter distended when in its operative position, saidclosure having a tongue to engage between the inturned portion and thead acent surface of the neck and adjacent walls of the neck portion, anda rigid in the presence of two Witnesses.
